Can we make it cost effective to utilize alternative energies at Woodward High School?

.
Entry Event:
Video pumped through the school followed by a blackout and discussion regarding what we would need to do if we were forced to find and utilize alternative energies. (Include video about the great black out in New York City a few years back.)
.
Thoughts to consider:
What are alternative energies? How are they produced?
What type of energy do we currently use? How is it produced?
What is the cost of our current energy?
